AGENT Illlll |NVE EDGA Filed June 6, 1956 to form slots 24 and 25 to respectively seat opposite margins of the hole 12. In this form the body 23 is formed with a transverse open sided compartment 26 arranged. and dimensioned to receive a core 14 through the side opening with its axis norm-al. to the plane of the board which is to hold, the unit. The ltop and bottom faces of the unit 23 are'respectively extended to provide a protective thickness for the top and bottom of the core 1'4. Preferably the extended portion of the top of the unit has a relatively small aperture 27 coaxial with the core for the passage of core leads. This form of the invention can be assembled on a board by distorting the bifurcated ends to enter a hole 12 as explained in connection with the unit of Fig. 1.

Referring to Fig. 8 of the drawings, another form of the invention is shown wherein the unit 30 is in the form of a resilient relatively thin dat plate having a T-shaped extension 31 on its bottom margin forming oppositely aligned slots 32 `and 33 for respectively seating opposite margins of a hole 12 in the panel 11. The shank portion of the extension 31 is complementally contoured to seat about the hole 12.

For mounting a core 14, a transverse through hole 34 is provided in the body dimensioned to snugly receive the core 14 and also provide means for anchoring the core 14. In this instance the anchoring means is an inwardly disposed nose 35 molded in the relatively thin flexible top which bounds the hole 34. In assembling this type of unit the extension 31 is distorted and pushed through a board hole 12 until its head snaps about the hole margin which then seats in the slots 32 and 33. When thus fixed in place the body rises perpendicular to the board ready to receive a core, which can then be pressed laterally into thc hole 34 forcing the iiexible top to distort so that the nose'35 rides over the t-op of the core to snap into coaxial holding position within the bore of the core. In this form of the invention the wound core can be located either before or after theunit is attached to the board.

In the form of the invention shown in Figs. 9 and 10, the resilient body is in the form of a flat shank 36 terminating at one end in a 4head 37 and at the opposite end in a base 38 for mounting the body upon a terminal board 11 with a provided base receiving hole 12. The shank 37 has a width less than the diameter of the bore of a core 14, and a length between the head 37 and the base 38 substantially' equal to the length of the core -14 whereby the core is anchored in assembled condition. The head 37 is generally convex to form relatively thin portions capable of being flexed to pass through the core of a core under distorting pressure, and emerge as a selfrestored retainer abutting one end of the core. The lbase 38 is formed with two opposite laterally disposed bifurcations 40 respectively forming slots 41 and 42, each of which in assembled condition seats a margin of the board 11. As finally positioned the core 14 coaxially encircles the shank 36 and is held firmly between the head 37 and the base 38.

It will now be apparent that the invention provides a novel unitary support structure for mounting components. In particular it provides a support structure aifordirig easy and economical assembly of magnetic cores on a mounting panel, while at the same time eliminating the aforesaid tedious hand-winding and cementing operations. Further, the components are supported by resilient units of lrubber or the like which afford effective cushioning and shock-absorbing. Since the-mounting body is of insulating material it is now possible to mount the units upon a metal chassis. Also by reason of the now possible close spacing of units in side to side relation more units can be mounted upon a terminal board than has been possible heretofore.

What is claimed is:

1. In a memory storage assembly for computers and the like comprising in combination, a panel having a plurality of spaced openings therein, a plurality of housings mounted in said openings, each housing being of resilient insulating material and having a compartment adapted to substantially enclose a memory storage unit therein, said housing consisting of an elongated tubular body portion and inwardly extending top and bottom end portions contiguous therewith for substantially closing the ends of said tubular portion, each end portion including an aperture axially aligned with the tubular body portion and being of a smaller diameter than said tubular body portion, a magnetic memory unit of larger diameter than said apertures received in said compartment, electrical windings around said unit and extending therefrom through one of said apertures, and grooved flanges extending outwardly from the tubular body portion and centered axially therewith, said flanges being received in an opening of said panel to mount said housing therein.

2. In a memory storage assembly for computers and the like comprising in combination, a panel having an opening therein, a housing mounted in said opening, the housing being of resilient insulating material and having a compartment adapted to substantially enclose a memory storage unit therein, the housing consisting of an elongated tubular body portion and inwardly extending top and bottom end portions contiguous' therewith for substantially closing the ends of said tubular portion, each end portion including an aperture axially alignedswith the tubular body portion and being of la smaller diameter than said tubular body portion, a magnetic memory unit of larger diameter than said apertures received in said compartment, electrical windings around said unit and extending therefrom through one of said apertures, and grooved flanges extending outwardly from the tubular body portion vand centered axially therewith, said flanges being received in the opening of said panel to mount said housing therein. f

3. In a memory storage assembly for computers and the like comprising in combination, a housing adapted to be mounted in an opening in a panel, the housing being of resilient insulating material and having a compartment adapted to substantially enclose a memory storage unit therein, the housing consisting of an elongated tubular body portion and inwardly extending top and bottom end portions contiguous therewith for substantially closing the ends of said tubular portion, each end portion including an aperture axially aligned with the tubular body portion and being of a smaller diameter than said tubular body portion, ya magnetic memory unit of larger diameter than said apertures received in said compartment, electrical windings around said unit and extending therefrom through one of said apertures, and grooved llanges extending outwardly from the tubular body portion and centered axially therewith, said ilanges beingadapted to be received in the opening of said panel to mount said housing therein.
